Abstract:
Object To study the influence of drought stress on imbibition germination of Glycyrrhiza uralensis seed and the drought resistance of its seedling. Methods To measure the imbibition rate, germination rate, seedling growth, relative tissue moisture content, relative electrical conductivity, SOD enzyme activity under drought stress simulated by PEG-6000. Results The imbibition rate, germination rate, SOD enzyme activity, and seedling growth present rising tendency then following by the decrease, while the relative tissue moisture content and the relative electrical conductivity tend to decrease. Conclusion The appropriate drought stress increases both the G. uralensis seed germination rate and the seedling drought resistance.
